1.3 gig tiff file freezes my machine - what now?

    I worked on a tiff file in Photoshop for quite some time.
    When I was done, I had a 1.3 gig file. Now, I can't even
    move it to another directory in Windows Explorer without
    freezing my machine.

    I don't know how it got quite so large :) But I do know
    I'd hate to lose all that work and go back to the original
    to begin again.

    I don't understand why it's freezing:

    P 4, 3.2
    2 gig of ram
    ATI Saphire Radeon 9600 Pro Atlantis - 128 DDR

    Help?

    Thanks.

    Photoshop 7

    This was a scanned negative - tiff file.

    As I worked, I periodically saved the file so as not to lose
    the work.

    You will need a very large pagefile and a very large PS scratch area to work
    with such files.

    Sorry for my ignorance:

    "pagefile" refers to virtual memory settings? What would
    you recommend for a pagefile setting given the specs of my
    machine.

    Does this have something to do with system cache? Because I
    sometimes use speech recognition software, I use a little
    utility called cacheset.exe from sysinternals.

    How do I set the PS scratch area?

    Thanks again.

    Not a single one of us was born knowing much about operating systems.
    I recommend letting the system determine the size of the pagefile.
    Not exactly. The pagefile is what XP uses so that it can pretend that there
    is more memory available than that allowed by RAM.
    The scratch area is really just a folder which PS uses for its temporary
    files. You can only help by defragmenting the drive so that XP can allow
    the amount of disk space allocated to the folder can be increased as needed.

    make sure you are log in as admin

    control panel >system>Advanced>performance>settings>advanced>virtual
    memory>you can see how much space is available and increase the paging file
    size to your liking

    IN Photoshop under Preferences>memory and cache options will show you how
    much RAM is available, usually you can increase this.
    under plug-in and scratch disks if you have extra drives or a removable
    drive you can use them for extra space too.

  7. So you are not using Photoshop at this point, you are just looking at
    the saved file in a Windows folder and trying to move it to another
    location? If so, I don't see how the Photoshop scratch or pagefile
    settings are relevant.

    If you are moving the file to another folder on the same logical hard
    drive partition (the same "drive letter"), Windows shouldn't even need
    to copy the file - it just changes the directory pointers. I can't
    imagine why it would freeze unless the directory structure of your
    drive is seriously damaged.

    If it is, that is what CHKDSK and Scandisk are for. Typically you
    would right click the icon for your drive, choose Properties, the
    Tools tab, and Error-checking. Safest plan is to run it without
    "Automatically fix" first, and see what it finds. Almost always it is
    safe to go ahead and let it fix errors. If it doesn't find any
    problems without "Scan for bad sectors", turn that on and try again -
    but be prepared for a wait measured in hours.

    If the destination is on a different partition, then the entire 1.3 GB
    needs to be read, and written to the new partition. If one bit of it
    can't be read, Windows may retry for a _very_ long time (I've seen
    over five minutes!), and appear to be frozen (Windows Explorer may be
    reported as "not responding"), before giving up and reporting a read
    error. Again disk Error-checking would be a good place to start.

    For detailed XP instructions:
    <http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q315265>

    Apparently if XP Chkdsk finds no errors, you get no report or log,
    just the "check complete 0" dialog. If there are problems you may need
    to look in the "Event Viewer" to see the details:
    <http://www.computing.net/windowsxp/wwwboard/forum/132863.html>

    The Event Viewer might also contain messages from a S.M.A.R.T utility
    provided by your drive vendor, or other drive-related messages.

    Earlier Windows versions created a Scandisk.Log file at the top of
    your Windows drive with full details of the scan.

    Can Photoshop re-open the file? If so you could then save it again to
    a new location.

    You might try a fractal compression.

    But really unless your're working to make a realy BIG print or to print
    on something that can print 400+ dpi @ feet x feet (and I don't know
    what printer that would be!) you shouldn't work in tiff for a file that
    big anyway - your sure it's a tiff, right?

    Something that big (1+ GB) should be a multi-layered PSD, maybe even a
    16 bit LAB PSD, and then convert down & flatten to 8 bit tiff to output
    the file. Tiff format files that size are good for archive purposes
    but I wouldn't work on one as a tiff if I could help avoid it.

    Check fragmentation on all partitions. Saving a file this big
    over and over can make a mess unless the partition is huge and empty.

    Hit ctrl-alt-del, pick task manager and learn how to make sense of the
    numbers in task manager. Look at View->Select Columns to see more
    system info.


    I hope the OP isn't using a Win98 machine :)

    OS ? I assume w2k or XP.

    We used to be able to crash NT on demand by opening a text file with a
    text editor when the size of the file was greater than the available
    pagefile space. We were opening 1GB+ text files and it was *very*
    reproducable once we figured out what was going on. Details on request.

    I suggest making a fixed pagefile size of at least 3GB so that PS can
    have a file, and a copy in pagefile plus some left over for the OS.

    This is just a WAG, but it's easy to do.

    whoops - I should have said - Win XP Pro

    I will defragment - hopefully that will help prevent this
    along with fixing virtual memory, scanning the drive, etc.

    You are joking, right?
    Photoshop's RAM requirements blimp-out on layers, but they are usually
    necessary. Saved TIFF can be BIGGER than a saved Photoshop file, especially
    the flattened PS file.

    Anywho, PS has limits. CS has it's new large file format and is happy with
    very large files.

    Now to the OP! Adobe has a document on their web site giving the steps one
    should take to lower the overhead of PS and CS. Seek it out. Following the
    directions can save your butt.

    Oh hell, it's easier than that to crash NT. :) Just create a file of a
    thousand backspaces or so and then from DOS just Type it! Blue Screen!
    Hum... haven't tried that with XP yet. I will in a minute.

    Many thanks to all of you for your very helpful suggestions.

    I now have:
    a 3 gig swap file
    Photoshop set to use a separate partition (I don't have
    another drive) for the scratch file.
    Photoshop set to use 75% of available memory

    I have defragged both the scratch file drive and the
    Photoshop Directory (I created a bat file that will do this
    anytime I run it so that I don't have to defrag the whole
    drive all the time).

    Things definitely are going faster and I am pleased with the
    speed increase.

    One more Question: When I did crash Photoshop, I got an
    error in gdiplus.dll. Does this provide any other clues?

    Thanks again.
